Miracast - waa maxay? signal warbaahinta gudbinta Wireless

multimedia wireless oo tayo sare leh oo ay muujin ka maskaxda si ay u qalab devaysa gaar ah (TV, borojektar, ciyaaryahanka Streaming ah, iwm ...) - tani waa dhab ahaan waxa ka danbeeya xilli Miracast. Technology Tani waxay tahay ficil suuqa sharci ah in wax soo saarka garaadka "xiran" Apple iyo Intel, in uu yahay, waxa dhaxlay mabaadi'da AirPlay iyo WiDi, laakiin waxaa waajib ah in a algorithms functional wax yar ka duwan yahay. Sida ku salaysan fursado caadiga qaaday Wi-Fi Direct. Sidaa darteed, macluumaad jidka ka renderer warbaahinta in la koobnayn labo dhibcood. Router-dhexdhexaadiye-socodka ah ee turjumaad ma aha qayb - ka diraha iyo qof qaata si toos ah ugu xiran.

Miracast. Waa maxay mucjiso this?

Xaq u gaar ah si ay summad ah (magaca buuxa ee astaanta ah - Wi-Fi Certified Miracast) urur uu leeyahay Wi-Fi Alliance. Si kastaba ha ahaatee, wax logos gaar ah ama gaabiyey calaamadaynta ee alaabta taageerada technology kajirin. Looxii «WiFi Miracast» waxaa inta badan laga codsadaa on qalab, ayaa maray nidaamka shahaadada la raacayo shuruudaha qorshaha baaritaanka Display ah.

Ujeedada ugu wayn waxaa diyaariyey sida soo socota :. "Si loo xaqiijiyo in wax soo saarka ee content warbaahinta ka monitor PC ama bandhigay qalab mobile shaashad weyn oo aan isticmaalka fiilooyin iyo shabakadaha dibadda" Iyada oo si gaar ah xooga on tayada signal ka helay.

Maanta user kasta waa devaysa "smart" (in taageerada caadiga ah OS Miracast ah) waafajinta kartaa qalab ay la a TV / borojektar iyo shaqeeyaan image baaxadda aan rakibidda software dheeraad ah.

astaamaha aasaasiga ah

sal asaasiga ah ee technology - a algorithms functional Wi-Fi Direct: Miracast-adabtarada in daboolaya galay unit HDMI dekedda-conjugate (haddii by the "bir ah" heshiis gudaha bixiyo), oo bedel ku ah qayb ka mid ah network guriga iyo dhistaa buundada la idaacadda a ganaax. Waxaa intaa dheer, signal format ITU-T H.264 halkan aan lagu arkin sida hab in ay is dhaafsadaan files, iyo sida qaab gaadiidka xirmooyin warbaahinta kaabsal (jadwalka loo soo diray oo helay qaab sida ay tahay).

Waqtiga soo bandhigidda Miracast (waxaa dhacday si sax ah in September 2012 - Lama filaan ma aha, in wax ka yar 2 bilood technology ayaa qaatay nidaamka hawlgalka Android updated iyo, sida, ayaa codsatay ma aha oo kaliya in wax soo saarka Google ee), waxaa jiray in ka badan konton qaraarada taageeray: 17 - EW, 29 - VESA, 12 - telefoonka waxa loogu yeero. Waxaa ka mid ah heerarka dhawaaq la garan karo - laba-channel LPCM, «rikoodh 5.1» AC3 iyo ACC.

Wixii macluumaad dheeraad ah oo ku saabsan habka xidhiidhka ka

Step by dardargelinta tallaabo fursadaha Miracast (waxa laga yaabaa inay hore u cad) oo ku lug leh dhowr tallaabo. Waa in aan u dhaqmaan sida hab:

1. Daar PC ah / casriga / "Xararad".
2. Daar xogta qadanayo '(ama screen TV for bandhigyo).
3. Ka dhig labada qalabka u dhiganta barnaamij horena.

Dooro oo ay maamulaan file gaar ah in hab naqilkii, screen bandhigay ku qaata warbaahinta monitor.

Router dhexdhexaadiyaha in "wada hadal" sida aanu ka qayb: laba qalabka sameeyaan channel toos ah ammaan ka badan taas oo markii danbe dhacdaa warbaahinta. In la eego fudud, Miracast (waa jihada farsamada sida nooc ka mid ah macluumaadka sawir iyo video shaqada noqon doonaa caan ka badan ka HDMI-albaab dhaqanka, hadda waa shaki ku jirin) waa naqshadaha dhisay on top of Wi-Fi Direct ka dib versions (3.50 iyo wixii ka sareeya). Waxaa loo adeegsaday H.264 video riixo oggol in cilinta nuqul ah saxda ah ee xubno ka data ee visualizer kasta atypical, oo ay ku jiraan shaashada qiyaas ah.

Faa'iidooyinka in by kasta dareemay

Xitaa user aan khibradda lahayn oo aan fikir wici lahaa sababo dhowr ah baahida loo qabo Miracast. Marka hore, waxaan ka hadleynaa raaxada ka hawlgala, la arki karo in midba midka kale "in ka badan hawada", iyada oo aqoonsiga dhacdaa xoogaa ilbiriqsiyo ah, iyo isdhexgalka - aan dhex- (uma baahna in ay iibsadaan cable xira). Marka labaad, saari-Miracast adabtarada waa iswada si sixitaanka doorashada for model gaar ah oo qalabka uma baahna - diraha dongle / aqbalana laftiisa aqoonsan macluumaad graphic. Intaa waxaa dheer, waxaa jira in ay taageero 3D ku saabsan asalka ah ee ammaanka buuxa ee content daayey.

Ka mid ah faa'iidooyinka kale:

• ay caanka ah ee caadiga ah ku tilmaamay xidhiidhka ee soo saarayaasha bulshada (in ka badan 500 shirkadood ayaa diiradda lagu saaray fulinta oo ka mid ah "muraayad ah baahinta");
• ma u dhac muuqata in processing signal (model darbi kharash yar qaanuunkan ma khusaysaa si buuxda);
• suuragalnimada in wareejinta "culus" video (FullHD);
• yaraynta ee geedi socodka dheeraad ah (laga saaray load xad-dhaaf ah oo ku saabsan batariga ee smartphone / kiniin).

Miracast iyo meelaha ay

Nasiib darro, iyadoo ereyada "aan duleella" ficil ahaan ma dhici karto in dunida ka mid ah farsamooyinka-sirdoonka sare. Xaqiiqada ah in version ee hadda Miracast ah (Android, waa in la yiri, waa kaliya mid ka mid ah nidaamyada hawlgalka badan that link ay qaddar la caadiga ah, laakiin in qeybta harag mobile ay xukunkiisa ma aha in shaki) waa cilladaysan, cadaynaysay:

• weli waafaqsan daciif ah (oo mararka qaarkood xaaladda "xiriir la filayo ..." waxaa soo bandhigay shaashadda, laakiin aqoonsiga hawlgalka oo aan ka heli kartaa macquul ah follow-up);
• taageeri doonnaa xallinta ugu badan ee 1920x1200, halka sii kordhaya baahida loo qabo 4K;
• isticmaalka codec H.264 lahaansho;
• degree badheedhi alaabta shareeraysaa in ay joogaan on software guddiga, iyo "hardware" si ay u hirgeliyaan technology (ma logos ku baakadaha iyo / ama guryaha devaysa).

Sidoo kale, dadka isticmaala badan arki khasaaro ah in marka la isticmaalayo a Miracast-qalab la joojiyo by hawlgalka ka mid ah caadiga Wi-Fi-la xidhiidha. A adabtarada 2-channel, sida aynu ognahay, ma dhammaan waxay leeyihiin casriga ah iyo kiniiniyada (deficit lagu arkay xitaa qeybta qurbaannada premium). Ugu dambeyntii, ka dynamics of 30 FPS iyo 720x480 - Processor heerka aad suubban maanta, laakiin daciif ah xitaa waxay mararka qaarkood ma heli fahamka on qayb ka mid ah Visualizer ah (on a screen video weyn la iman jerks dareemi).

Analogs iyo khilaafaadka ay aasaasiga ah

nidaamyada hawlgalka, saaxiibtinimo-ku fikiray inuu Miracast, - Android (tan iyo version 4.2 Jelly Bean), Windows 8.1 (waayo, desktop iyo qalabka mobile) iyo Amazons Naarta. Sida PC ku salaysan Linux, ka dibna iyada oo aan jabiyay gaadho aqoonsi ku filan u hagaagsan oo badeecada shahaado ma libaanaan. Si kastaba ha ahaatee, huck waa ben la fashilaad iyo ma damaanad qaadi karno wadahadal caadi ah u dhexeeya diraha iyo qaataha ah ee content warbaahinta. Wakiillo ka kala duwan ee Apple meelayan ogayn Miracast, sida "xiraa" hoos AirPlay asalka technology madal.

Xad Intel WiDi la odhan karaa in xidhiidhka ka caadiga ah muddo dheer, waxaa la taagan yahay sidii hantida isku magaca by shirkad iyo jiray maqan qalabka la Processor-saddexaad. Laakiin la sii daayo of version 3.5 oo ku saabsan in ay si qoto dheer beddelo waa.

dhigooda St Paul kaliya labo - MHL iyo HDMI. Of faraqyo muuqdaa xusid mudan xiriir cable saldhig, taas oo aan ku haboon marka qayb ka mid ah u hagaagsan iyo signal ah xasiloonida is waydaarsiga xogta firfircoon (Miracast ku ool ah "sags", marka shaashadda fool tallaabo-Muuqaallo).

Miracast indhaha u soo saarayaasha in

Inkastoo technology iyo leedahay code il furan, algorithms ay kala iibsiga image wireless ugu horayn waxa diiradda on iman kara ee Windows iyo Android. Ma aha la yaab leh in liiska saarayaasha imaanaynaa wakhtiyada, dhawr boqol oo jagooyinka. Run, waxaa ka reeban iyo nidaamka xun la xiriira update qolof maamulka. Sayidka, gaar ahaan, aan la taageeray by Miracast Windows 7 (iyo arrinta aan lagu xalin ama shirka copyright ama rakibidda software kaabayaal ah).

The noocyada ugu garan karo, arag "jacayl" for Wi-Fi Direct iyo H.264:

• Qualcomm.
• MediaTek.
• AMD.
• Microsoft.
• Intel.

mustaqbalka dhow la booska Miracast

Fikradda aasaaska wireless HDMI ah, dabcan, oo xiiso leh. Si kastaba ha ahaatee, soo bandhigay ee ku saabsan xogta screen weyn ka smartphone ama kiniin ah ma aha sidaas u adag tahay. Halkee dhib - si aad u hesho a hufan SMARTs maamuuska kale. Oo saaraysa, Miracast waxaa kaliya oo aan si habsami leh u socday.

Ka sokow tartamaya toos ah - AirPlay iyo Chromecast - dhaqmaan daqiiqado qaar badan "xariifnimo". Tusaale ahaan, waxay u oggolaadaan in aad soo diri video content shaashadda weyn halka u dhex maraan iyada oo menu ah (aan muujinaya, kuwaas oo faahfaahin isla webigu ku qaado). midka xun Second timaado in loo maqli karo hab - Miracast inta badan ciyaara video ah ilaa ugu dambaysta, ma ficil midkood shidma ama shidma booska amarka / il devaysa dhaqdhaqaaqa (conjugation buuxda u ballanqaaday in firmware cusub, ka dibna "hurda" smartphone barto in uu dami screen qiyaas oo aan code dheeraad ah user).

Hadda oo ku saabsan sinaanshaha oo la technology DLNA ah. Miracast - a "Jid Toosan baahin" images live "ka shaashadda of qalab on monitor ka duwan dhacdaa on geynta ugu gaaban oo aan wax qanjidhada isgaarsiinta oo dheeraad ah. Under soo gaabiyay DLNA dhuuntaa heerarka raznosortnyh isku jira oo dhan. qalabka Ie lagu dhisayo is faham wadaaga baahan yahay joogitaanka "turjubaan" (router). Oo haddana, ka qaybgalayaasha Digital Living Network Alliance shaqeyn karaan oo kaliya files, iyo laba "Saaxiib" Miracast shaqada on mabda'a muraayadda ( "show in, ka dibna u gudbin"), iyo xalinta dhibaatooyinka farsamo gaar ah la wadaagi kartaa content in .Wadashaqayntaas si mug leh.

Software Miracast waafaqid: Windows-version

On rasmi ah bogga Microsoft waxaa ku qoran warar ku saabsan xaaladaha qalliinka looga baahan yahay, taas oo ay suurto gal tahay inay soo bandhigto go'an functional of technology Miracast.

Windows 8.1 - pre-rakibay ama updated la "qaad" - waxa loola jeedaa tirada ugu yar ee looga baahan yahay. Intaa waxaa dheer, ku dhawaaqay of applicability ee caadiga ah si ay version daayey RT 8.1 iyo shirarkeeda OS ka dib.

diyaarinta computer / qalab for wireless content warbaahinta on kormeeraha

Waayo, qalabka la "sideed" sabuuradda liiska falalka si loo hubiyo in hannaanka baahinta, booguhu waxay ku dhaadhacay labo dhibcood:

1. qalabka .Wadashaqayntaas (gudbiye iyo qof qaata) ku jira aagga caymiska signal a.
2. Dardargelinta "Projector" doorasho.

Waxaana jira dhowr xaaladood ee wax soo saarka content. Picture / video, waxaad:

• baahiyey hab nuqul (bandhigay isku mar 2 qaab);
• arki kaliya monitor ee hay'adaha aqbaliddoodii;
• wareejiso by jiidayeen waxyaabaha la doonayo ka screen si screen.

Miracast iyo Android nidaamka ka hawlgala

Dad badan oo soo saarayaasha korontada ayaa isku dayaysa in ay sameeyaan ugu of technology Miracast. LG ayaa, tusaale ahaan, waxaa la midaynaysa ee casriga ah iyo telefishannada ayaa muddo dhowr sano ah. Ha ku Hadhi iyo injineerada Sony, Samsung, Panasonic - meel kasta oo ay jiraan waxaa socda Android ka weyn yahay 4.2, Heerka this waxaa fuliyey, sida ay yidhaahdaan, si buuxda.

Baahida loo qabo gudbinta raaxo of content keentay in xaqiiqda ah in taageerada Miracast xitaa helay kuwa lagu daydo TV oo heshay off line kiniisadda ilaa 2012. xal Technical noqday HDMI-gaar ah furayaasha (adapters signal). Waqtigan xaadirka ah, waxay ku hawlan yihiin soo saarta daraasiin shirkadaha kala duwan. Sidaas darteed, waxyaabaha soo socda suuqa, iyo si xun u kala duwan yihiin qiimaha iyo tayada. Waxaa intaa dheer, meesha uu ku noqon karo iyo dheelitir la'aanta functional: mid adabtarada awoodda ay u dhisaan "buundooyinka" Heerka Miracast gudahood, kale uusan wax kharash ah si aad u hesho "dhulka caadiga ah" leh devaysa Apple ama la dhiso a "wada hadal" on DLNA ah. Taasi waa sababta ka hor ay muhiim u tahay gudidoodu naadiyada mowduuc iyo booqo goobaha rasmiga ah ee saarayaasha iibsato.

muuqaalka guud ee dongle ugu caansan

on Miracast Dongle qiimaha kala duwan ee kala duwan 30-100 cu ah. Ka dib markii ay u iibiyay kuna rakibay adabtarada ee shiidaa TV kasta oo qalabaysan HDMI-dekedda, ayaa loogu xidhi karaa qalab wirelessly. Waxaan ka hadleynaa xiriir toos ah oo kuu ogolaanaya in aad u ciyaaro video "weyn" ee 1920x1200 format.

Dongle Mocreo (.. 30-35 cu) - taageero damaanad qaaday saddex hab maamuuska: Miracast, AirPlay iyo DLNA.

"Furayaasha" masaseed brand (70-80 at. E.), Caadi ahaan aqoonsan heerarka la mid ah sida Mocreo ah.

GeekBuying adabtarada (50-60 cu ..) - bixisaa warbaahinta muraayad on algorithms Miracast iyo DNLA.

Intaa waxaa dheer, waxaa jira ganacsi la heli karo iyo asalka dongle Wi-Fi Certified Miracast, saxar ka yar hal nooc oo signal.
